What is the formula and molar mass of beryllium chloride?

Answer 1

#BeCl_2# has a molar mass of 79.9176 amu

Recall that the formula mass is the sum of the atomic weights of the atoms in substance while it is in its empirical formula, and that the atomic mass is the weight of precisely one mol of the substance.

We have Beryllium chloride which is an ionic compound that forms a crystal lattice, the formula #BeCl_2# tells us that #BeCl_2# is the simplest repeating unit that forms the crystal lattice.

Since this is an ionic compound, #BeCl_2# is a formula unit, not a molecular formula.

It's mass is 79.9175 amu.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
